4.0 SAFETY CONSIDERATIONS

Note: This operating and installation manual is intended for use by a competent programmer, electrician, technician, or engineer. The instructions included in this manual should be read and kept as a reference document prior to initial controller installation and use. Incorrect operation of these controllers can present a significant threat to both individuals and equipment. In the event of an equipment break down, do not attempt to repair the controller as there are no user serviceable parts inside the enclosure. Any evidence of tampering will invalidate the warranty.

5.0 APPLICATION

This operating and installation manual should be used in conjunction with the online help provided with the Pro-FX Control 1.1 development environment. Together, this information should form a basis for the simple configuration of the controller and the creation of programs specific to your application needs. Proper operation of the controller is dependent on the program that is created and ultimately downloaded to the hardware, therefore extensive testing is required.Customers programming the controller possess the responsibility of ensuring that both the hardware and software performs as intended with their applications.

Note: That each controller within the HFX product family requires the installation of hardware-specific firmware, description files and libraries before initial use in the application environment.

6.0 HARDWARE DESCRIPTION

The Eaton HFX product line consists of four controller models (HFX12m, HFX20m, HFX32m, and HFX48m), each possessing a unique number of I/O. The HFX12m/HFX20m (pictured below) and HFX32m/HFX48m (pictured below) both share common housings.

Each of these units is designed to function over an extended operating range of supply voltage, from 6 – 32 VDC.

HFX12m/HFX20m

HFX32m/HFX48m

The three integrated CAN ports on these units support CAN 2.0B, the first of which also possesses a software configurable termination. Both SAE J1939 and CANOpen stacks are available in the software development environment.Additionally, the CANLayer2 software library is available for use with CAN bus.

HFX controllers are programmed via a standard USB port. The gateway from a user’s computer automatically detects the hardware, eliminating the need to manually assign a COM port to the unit.The two regulated outputs (sensor supplies) can be configured individually for either 5 or 10 V operation.

HFX Product Family


12.0 FUNCTIONALITY AND BASIC OPERATION

12.1 Controller Startup

At initial startup, the controller enters the bootloader. A bootloader is simply a small program that loads the rest of the firmware when the controller is initially powered up. This firmware resides in the flash memory and provides the necessary memory mapping and instructions for the controller, allowing the application program to be processed. The bootstrap mechanism provides the means to enter the bootloader. The IEC bootstrap mechanism is as follows:

1. Check for PWM1&2 ≥ 11.0 V

2. Delay 3 seconds

3. If either the HFX service tool or IEC is connected, abort and don’t load IEC app from flash

4. Otherwise, load and run the IEC app in flash like normal.

This provides a mechanism to remove a frozen application.

1. Load a new application, or

2. Reset origin will clear entire application memory.

Boot Process

Continue Booting & Load IEC from flash

Yes

No

No

PWM 1&2 ≥ 11 VDC

IEC or HFX service tool is connected within

Yes

Abort and don’t load IEC app from flash

12.2 Sleep Mode (Time Delay Operation)

Sleep Mode provides a mechanism to have a controlled shutdown of the vehicle control system.This is a benefit because the unit can be put into an idle state where less current is required thus extending battery life. It is also useful with applications where, prior to shut down, the controller needs to return key functional outputs to a predefined or home position.

Operating Enter Sleep Mode bit State Sleep Allowed State

Sleep True True (Sleep Pin> approximately 6.6 V or Ignition Pin < approximately 6.6 V)Awaken False False (Sleep Pin< approximately 6.6 V and Ignition Pin > approximately 6.6 V)

The controller will enter sleep by setting the sleep bit anytime that the sleep allowed bit is true( Sleep is high or IGN is low or not connected).

The controller will awaken from sleep if Sleep is low or not connected and IGN is high

Sleep current 2.4 mA, @ 10 V, 1.9 mA @ 15 V, 1.6 mA@ 20 V, 1.2 mA @ 25 V

12.3 Task Configuration

The maximum number of tasks is 5. The controller supports the following tasks:

• Cyclic: Task processed in a predefined time.

• Freewheeling: Task processed as soon as the program is started. When complete, it will automatically restart in a continuous loop.

Note: There are no external events available to trigger task execution.

HFX Product Family


12.4 Watchdog Operation

Watchdogs are present to provide an indication that something has gone wrong. Systems that are programmable can hang for a number of different reasons. One of the most common is the execution of an infinite loop due to a programming logic error This type of failure prevents any of the other code from executing. Also, if an unusual number of interrupts arrives during a single cycle of the loop this can prevent the main loop from having sufficient time to execute. Another possibility is a failure in hardware that causes a constant reset.

Each controller has an internal hardware watchdog that is continuously running in the background to

monitor for a system malfunction. This watchdog is not user serviceable and is not visible to the user. It will trigger in the event of a task timeout and can only be reset through a hard reset of the controller, which means that the user must connect the service tool or IEC programming tool to the controller, tie PWM 1 & 2 to supply voltage, and then power up the unit. This will prevent the IEC application code from loading.

Each controller also features a second watchdog, which monitors the Pro-FX Control runtime system with a default value of 2 seconds and recommendation to be set above a minimum 100 ms. This is user configurable via the System Config Configuration tab (see below screen).

Note: That this watchdog is reset using the same protocol used to reset the internal hardware watchdog.

Pro-FX Control also has a watchdog that monitors specific tasks; the time is user configurable via the Task Configuration/MainTask tab (see below screen). For additional details see Pro-FX Control online help. It is typically reset by resetting an associated fault.

HFX Product Family

12.5 Controller Memory

The controller utilizes an advanced superscalar 32 Bit processor operating at 200 MHz. The memory is arranged into the following areas:

• ROM Flash 3.75 Mbyte (1.75 Mbyte reserved for IEC application)

• EEPROM128 kbyte reserved for internal use i.e. firmware/bootloader

• RAM 256 kbyte

• MRAM 32 kbyte (24 kbyte user accessible file-system + 4kbyte redundant retain)

12.6 Remanant Variables

These are variables that can retain their value throughout the usual program run period. They are declared as 'Retain Variables', or even more stringent, as 'Persistent Variables'. For each case, a separate memory area is used.

The declaration determines the degree of "resistance" for a remanent variable in the case of resets, downloads or a reboot of the PLC. In applications, the combination of both remanent flags will be required.

The following table indicates how variables behave. VAR PERSISTENT/ VAR RETAIN PERSISTENT/ Online VAR VAR RETAIN VAR PERSISTENT RETAIN

Power cycle - X XReset warm <application> - X XReset cold <application> - - XReset origin <application> - - -Download <application> - - X

12.7 File System Operation

HFX provides a file system in MRAM to store additional information persistent through power cycles and application download. MRAM is faster than Flash memory and EEPROM and allows a virtually unlimited number of write cycles.

Using a file system for this purpose allows the most efficient use of memory and provides the advantage of being able to work with configuration files using the file system viewer in Pro-FX Control. Due to the speed and byte-level access of MRAM, interacting with this file system is extremely fast.

The following file operations are supported:

• SysFileClose

• SysFileCopy

• SysFileDelete

• SysFileEOF

• SystFileGetName

• SystFileGetPath

• SysFileGetPos

• SysFileGetSize

• SysFileGetSizeByHandle

• SysFileGetStatus

• SysFileOpen

• SysFileRead

• SysFileRename

• SysFileSetPos

• SysFileWrite

Details on using these functions can be found in the Pro-FX Control Online Help system.

13.2 Recommended Wiring Practices

This section contains information about the controller connectors and pin outs. Please use the following recommended wiring practices when installing and using the controller:

• Ensure correct and adequate single point ground to prevent ground loops.

• Use twisted or twisted shielded pair cable for CAN per the applicable standard.

• Confirm that the CAN network is properly terminated using 120Ω resistors.

• Ensure the appropriate sized conductor cross section is specified for the intended load current in the harness design.

Note: Please review individual overcurrent shutdown values in the configuration and use the correct wire gauge conductor to accommodate maximum load current configured

• Make sure that voltage drops are kept within reasonable levels under maximum continuous load conditions e.g. 1 volt on 12-volt systems and 2 volts on 24-volt systems.

• Verify that the harness is constructed to meet the needs of the application environment (e.g. shock, vibration, moisture, temperature, chemicals, and impact).

• Make certain that the harness is designed and constructed to minimize induced interference resulting from EMI coupling between signal wires.

• Separate power circuits from low-level signals.

• All splices (soldered or crimped) should use adhesive lined heat shrink tubing.

• Make provisions for drip loops to attach devices in exposed locations and prevent moisture entry and formation.

• Provide sufficient clearance from moving parts.

• Wires routed through holes in the vehicle body/chassis should use grommets.

• Avoid sharp metal edges, fasteners, and other abrasive surfaces or use protective shielding when routing harness assembly.

• Route wires to avoid exhaust system components or other high temperature areas, use appropriate heat shielding or other insulation where routing is a problem.

• Avoid routing near wheel wells or provide adequate mechanical protection to the assembly.

• Use a protective fuse sized appropriately for the controller supply current.

Note: typical maximum load current is 60% - 80% of fuse rating. Verify that wiring can handle more current than the fuse rating. Note the following guideline for maximum fuse recommendations:

• All Units: +VBat = 2 A

• HFX48 :+Load total < 50 A depending upon anticipated load requirements.

• HFX32: +Load total < 42 A depending upon anticipated load requirements.



! Warning: Prior to Welding

In order to avoid damaging the HFX controller ensure that all electrical connectors are fully disconnected from the HFX controller prior to welding on the machine.

15.0 CONFIGURATION

15.1 System Configuration

The controller features an advanced view into the hardware through the System Config I/O Mapping tab. There are numerous predefined variables associated with the controller that are accessible via the application program. This dramatically simplifies programming. All of these variables are pre-mapped with a relevant name linked with their respective channel. This name can be changed by the user

if desirable. Each variable also has an associated address, type, and description all intended to help the programmer. The System Config I/O Mapping is organized into folders of related variables e.g. the System State folder contains information such as Supply Voltage, Regulator Voltage, Ignition Pin Voltage, Sleep Pin Voltage, User LED State, USB Connected, etc. The other folders consist of System Information e.g. Firmware Rev, Serial Number, Hour Meter, etc.; Internal Relay status; Global Fault Status for both active and historic faults; and a Fault Monitor for managing faults (see below image).

The above variables can be monitored in the application program to alter controller response. For example, if the battery voltage falls below a predefined limit, or the temperature exceeds a limit, the programmer can choose to initiate a shutdown. Some variables can also be manipulated in the application control program. For instance, the user LED can be used to impart additional information to the user and the internal relay current can be monitored, and if it exceeds a predetermined limit, forced off.

Note: The variable radio button “Always update variables” (located in the lower right corner of the above picture) should be checked. If this is deselected, only variables used by the IEC application will be updated.


HFX Product Family

The system configuration has a second tab, the system config configuration that enables the user to configure settings for Regulator Voltage, CAN 1 Termination, Watchdog Time, and Low Memory Fault threshold.

Note: That depending on the parameter, double clicking the value in the appropriate value field will either open a drop down menu to select, allow direct editing or toggle the variable (see picture below).

15.2 Input Modes

The controller has either 6, 10, 16 or 24 inputs available for use, depending on the selected model.The specific inputs are as follows:

• Configurable Analog/Digital Inputs

• Configurable Frequency/Digital Inputs

• Configurable Differential Frequency/Digital Inputs

These different configurations are possible through selection of the appropriate mode in the PLC configuration tab in the IDE (see screens below).

15.3 Analog Configuration

Above is the Analog/Digital Inputs I/O Mapping tab.

This is the area where analog or digit input values are mapped to addresses. These variables are all accessible in the application program.

Variables:

• analogInValueX: Analog value with units dependent upon configured mode.

• analogInBinaryX: Digital value after debounce and rising/falling voltage thresholds are applied

16, 10, 6, or 4 of the inputs (depending on the model chosen) can be configured as either Analog or Digital.Both the Analog and Digital value have a name, value, address, type and description associated. The name can be altered by the programmer, if desired. Analog Inputs are displayed in actual engineering units depending on the mode configuration (either Voltage – mV, Current – μA, Resistance - Ω, or Temperature °C). Binary inputs are evaluated as true or false and our bits.


HFX Product Family

Above is the Analog/Digital Inputs Configuration tab.

The programmer changes the configuration of an individual input using the AIN mode value drop down selection.

Note: That if any of the following auto configurations is selected offline, the state for the corresponding pull-up, pull-down, and current shunt will change once the program is downloaded into the application controller.

Variables:

• AIN mode: This represents the type of input connected.

• Pull-up enabled: This is used in manual mode to activate the Pull-up resistor.

• Pull-down enabled: This is used in manual mode to activate the Pull-down resistor.

• Current shunt enabled: This is used in manual mode to activate the Current shunt resistor.

• Filter time constant: This is a low pass filter time constant that the input passes through, this is useful if you wish to filter out some random variation on the input or if you wish to reduce how quickly the input changes value.DIN debounce: This is a time value used to debounce mechanical switches that would otherwise trigger the input multiple times when closed.

• DIN rising threshold: This sets the lower limit voltage level necessary for the input to register as high.

• DIN falling threshold: This sets the upper limit voltage level necessary for the input to register as low.Used in conjunction with the above DIN rising threshold, an appropriate hysteresis level can be defined.

• Over-range limit: This sets the upper range limit for the associated over range fault.

• Under-range limit: This sets the lower range limit for the associated under range fault.


HFX Product Family

16.0 ANALOG INPUT CIRCUIT (PASSIVE REPRESENTATION)

The options are as follows:

Manual Config mode:

• Pull-up configurable

• Pull-down configurable

• Shunt configurable

Note: The manual mode is useful when connecting binary sensors. If you have a sensor that is switching ground to the input, you should enable the pull-up and set the rising threshold appropriately for the sensor (normally 2500 mV). If you have a sensor that is switching battery voltage, you should enable the pull-down and set the falling threshold appropriately for the sensor (normally less than half the battery voltage). Make sure to take into consideration the effect of hysteresis i.e. have some margin between rising and falling thresholds.

0-5 V mode (ratiometric):

• Pull-down forced off



0-5 V mode (absolute):




0-10 V and 0-34 V mode:

• Pull-down forced on



0-22 mA mode:

• Pull-up forced off


• Shunt forced on

Thermistor raw mode (output the 10 kΩ to 50 kΩ value):

• Pull-up forced on


• Shunt forced off

Thermistor #1 & #2 mode (output the temperature value):

• Pull-up forced on


• Shunt forced off

The status of the Pull-up, Pull-down, and Shunt are displayed for convenience. In Manual Config, the programmer has complete control to alter these values.

Each of the analog modes offers a user adjustable filter.The purpose of this is to smooth an input signal and/or limit how quickly it is changing. The filter is a digital approximation of a first order series RC network (low pass filter). The adjustable time constant is equivalent to the product of R*C in a conventional RC filter. The input should follow the following curve approximately (+/- 10%): 63% of the new step-response value after 1 time constant - after 2 time constants you will get to 86% and after 3 you will get 98%.

The digital mode features adjustable rising and falling threshold levels. This is intended to offer additional flexibility in input device selection. There is also a debounce associated with each input. It is only intended for digital use (mainly to prevent inadvertent input triggering from multiple mechanical contact closures). The debounce has a user configurable time period. Each digital input can function with either Low Side or High Side input types.

Additionally, each of the modes offer a user configurable under-range and over-range limit coupled to respective fault bits.

Note 1: There is an overcurrent fault that triggers when the input exceeds approximately 23.5 mA for 25 ms in 0 – 22 mA mode.

Note 2: Ratiometric mode compensates for the measured regulated output voltage variance and normalizes the input value relative to 5 volts.


HFX Product Family

Note: Thermistor #1 & #2 modes display value based on two user configurable lookup tables, see below:


16.1 Thermistor

We use 22 kΩ Pull-up resistors in this mode and therefore recommend that you use resistances in the range of 10 kΩ and 50 kΩ for optimal performance. The defaults shown above were derived from measuring an actual 100 kΩ thermistor.

16.2 Frequency Configuration

Above is the Frequency/Digital Input I/O Mapping Tab.

The tab displays the following: Selected Input, Variable, Address, Type, and Description. The tab also has predefined measurements of Voltage, Duty Cycle, Phase Angle, Pulse Count, Frequency, and Digital Value.

Variables:

• digitalInVoltageX: This is the voltage present at the input pin.

• digitalInDutyCycleX: This is the measured duty cycle at the input pin.

• digitalInPhaseAngleX: This is the phase angle relative to the channel pair defined in the configuration

• digitalInPulseCountX: This is a rolling pulse counter.

• digitalInFrequencyX: This is the measured frequency of the input waveform.

• digitalInValueX: This is the digital value after debounce and rising/falling voltage thresholds are applied.

HFX Product Family


Above is the Frequency/Digital Input Configuration tab.

This tab allows the user to configure any of the frequency input tabs.

Variables:

• Termination mode: This is where the combination of pull-up and pull-down resistors is configured.

• DIN debounce: This is the time value used to debounce mechanical switches that would otherwise trigger the input multiple times when closed.

• DIN rising threshold: This is the rising threshold voltage for digital inputs (effects the digital value only).

• DIN falling threshold: This is the falling threshold voltage for digital inputs(effects the digital value only).

• Phase channel pair: This selects channel pair used for phase comparison (1 is 1st pair, 2nd is 2nd pair, etc.).

• Filter time constant: This is a low pass filter time constant that is used on the following values: frequency, duty cycle, and voltage measurements.

• Over-voltage limit: This is the upper limit used for the over-voltage fault.

• Lower-voltage limit: This is the lower voltage limit used for the under-voltage fault.

• Frequency rising edge threshold: This enables either the adaptive (peak-detect) rising edge voltage threshold or the fixed 2.2 V threshold for the frequency circuit.

• Frequency falling edge threshold: This enables either 1.0 V or 0 V as the falling edge voltage threshold for the requency circuit.

This tab enables the programmer to change the configuration of an individual input using the termination mode value drop down selection. The options are as follows:

HFX Product Family


17.0 FREQUENCY INPUT CIRCUIT (PASSIVE REPRESENTATION)

Open Circuit mode:

• Pull to VLoad

• Pull to 5 V

• Pull to Ground

• Pull to 5 V & Ground

The digital input mode functions as it does with the Analog/Digital Input Configuration. It features the same set of parameters for configuring debounce, rising threshold level, and falling threshold. These inputs also support both Low-Side and High-Side input types. Although it is dependent on the specific sensor, normally in the case of a high side input (input is connected to ground), the Pull to VLoad should be selected. In this case it is important to make sure the sensor is rated for the full load voltage. Normally in the case of a low side input (input is connected to Battery +), the Pull to Ground option should be selected.

There are 8, 6, 4, or 2 inputs that can be configured as Frequency depending on the model selected. Inputs 1 and 2 have the additional capability to handle differential signals i.e. VR inputs on all models. When measuring phase, do not mix Inputs 1 and 2 with any of the other frequency inputs. The differential inputs also work with single ended sensors. In order to use these, just ground the input on the differential pair.

Note that the VR input can be configured with preset rising (2.2 V) and falling (0 or 1 V) thresholds for the measurement of our proprietary adaptive algorithm which compensates for large increases in peak level that are common with these types of sensors. Due to the nature of the circuit design used in the differential frequency inputs, duty cycle calculation is not supported on these two channels. Additionally, note that the accuracy of phase measurement is more limited than with the other 6 channels. Also, when measuring frequency, phase, pulse width, or count, the measurement limit is the shortest detectable pulse i.e. 20 μS. When using inputs configured as Frequency, voltage indication is not supported. Also note that the debounce filters are not intended for frequency inputs in general. When using channels 3 – 8 as frequency input, these are single ended inputs and trigger on 3 volt rising and 2 volt falling.

Note: That there is a fault that trips if the combined input frequency of all channels exceeds 200 kHz. This does not stop operation, but is intended as a warning that you are exceeding the limits of what the hardware can measure.

Note: When any of the above channels are configured as digital (HS or LS) the sampling frequency is 200 Hz. The debounce filters are intended for this mode.

17.1 Output Modes

The controller has either 6, 10, 16, or 24 outputs available for use. The outputs are all configurable as High Side Digital (ON/OFF), PWM open loop voltage, PWM(i) closed loop current control. In addition to these options a group of outputs support Low Side Digital Output (ON/OFF), PWM

1. High Side Switch (HS): This mode of operation is the standard output to turn a load on or off. The individual outputs can switch up to either 2 or 4 A loads depending on the output selected. This mode also supports PWM to drive a load propor-tionally.

2. Binary: This mode is intended for strictly on/off switching of a load.

HFX Product Family


Above is the Current/PWM Outputs I/O Mapping tab.

This tab displays the desired current, actual current, desired PWM duty cycle, actual PWM duty cycle, and the binary output status.

Variables:

• desiredCurrentX_XA: This is the desired output current for the channel. Note: That this is only active in Current Control mode.

• measuredCurrentX_XA: This is the average current measured over a single dither period.

• desiredDutyX_XA: This is the desired PWM duty cycle. Note: That this is only active in PWM mode.

• actualDutyX_XA: This is the PWM duty cycle commanded by the hardware.

• binaryOutputX_XA: This is the commanded output state of the high or low side output (false: open or True: closed). Note: That this is only active in Binary mode.

HFX Product Family


Above is the Current/PWM Outputs Configuration tab.

This tab displays indications that reflect faults associated with the outputs (i.e. short to Vbat, short to ground, open circuit, over current, and loss of control). Additionally, the individual channels PWM Frequency, Dither Frequency, Dither Amplitude, Drive Mode, Fault processing, Proportional, and Integral gain can all be configured here.

Variables:

• PWM Frequency: This is the fundamental frequency used to drive the output driver (note) that this must be ≥ Dither Frequency. The 2 A outputs support a maximum of 2 kHz & the 4 A outputs support a maximum of 500 Hz.

• Dither Frequency: This is the frequency that modulates the PWM duty cycle signal (note) that this must be ≤ PWM Frequency.

• Dither Amplitude: This is the amount of peak to peak variation in % of PWM duty cycle used for dithering.

• Drive Mode: This selects between closed loop current control mode or open loop PWM duty cycle mode.

• High or Low Side: Selects between a high or low side driver for the channel (note that this only applies to 4 A channels).

• Enable Channel Faults: Select to enable automatic system fault processing for this output channel.

• K_p: Proportional gain for current control loop.

• K_i: Integral gain for current control loop.

Shared Variables:

• DUTY_HS: High Side PWM duty cycle commanded < High Side PWM measured indicates a short to battery fault.

• DUTY_LS: Low Side PWM duty cycle commanded > Low Side PWM measured indicates a potential short to battery fault.

• VLOAD_RATIO: Measured output voltage > commanded output voltage indicates a potential short to battery fault.

• OPEN_DUTY: Commanded duty cycle > measured duty cycle indicates a potential open load condition.

HFX Product Family


• OPEN_CURRENT: Commanded current > measured current indicates a potential open load condition.

• GND_SHRT_DUTY: Measured low side duty cycle < commanded indicates a potential short to ground condition.

• GND_SHRT_VRATIO: Measured voltage < commanded voltage indicates a potential short to ground condition.

• MAX_CURRENT: The value selected here sets a software limit for monitoring individual High Side output current. If the measured current exceeds either the hardware limit or the value defined here, it will cause the Over Current fault.

• OFF_CURRENT: If Duty Cycle = 0% and measured current > OFF_CURRENT value defined here or the measured reverse current > 75 mA the Loss of Control fault will be triggered.

17.2 H-Bridge

The HFX 4A PWM output channels have hardware support for both High-Side and Low-Side drivers. Starting with HFX Support Package 1.1.0, an H-Bridge mode is also supported. This corresponds to Firmware Minor version of 21622 on the HFX, as reported by the HFX Service Tool. H-Bridge mode supports PWM mode but not closed loop current control. 4A PWM outputs can be paired in any combination in H-Bridge mode. For an application to pair outputs, it is critical they be configured with the same frequency. All remaining synchronization is handled automatically in the firmware, including a 50µs dead time.

Each leg of an H-Bridge is individually given a command between -100% and 100%. A positive command closes the Low-Side driver and switches the High-Side PWM corresponding to the command value. The inverse occurs for a negative command. A command of 0% switches off both sides.There are a number of strategies to work with H-Bridge. For thermal efficiency, the recommended approach is Low-Side switching.

The following function block provides an example of how to work the H-Bridge with Low-Side switching:

FUNCTION_BLOCK HBridge VAR_INPUT Command : REAL; HighSideCurrent : REAL; LowSideCurrent : REAL; END_VAR VAR_OUTPUT HighSidePct : REAL; LowSidePct : REAL; MeasuredCurrent : REAL; END_VAR IF Command >= 0 THEN HighSidePct : = 100.0; LowSidePct : = -Command; MeasuredCurrent : = HighSideCurrent - LowSideCurrent; ELSE HighSidePct : = Command; LowSidePct : = 100.0; MeasuredCurrent : = -(LowSideCurrent - HighSideCurrent); END_IF

The block would be used in an application like this:

18.0 OUTPUT CIRCUIT (PASSIVE REPRESENTATION)

18.1 Overcurrent Shutdown

The individual outputs of the unit are fully protected and will switch off if overloaded. When diagnostics are enabled and an overcurrent event occurs, the output will switch and remain off until another off/on command is received. The overcurrent shutdown is dependent upon the specific output. 2 A rated outputs have a slow blow level of approximately 2.1 A and a fast blow level of approximately 2.4 A. 4 A rated outputs have a slow blow level of approximately 4.1 A and a fast blow level of approximately 4.4 A. All outputs are additionally protected via an internal solid state relay. The relay can be active monitored for current and controlled in the user program.

19.0 PWM

19.1 What is PWM?

PWM stands for Pulse Width Modulation. It is a method that can be used to efficiently drive solenoid valves. Typically the output device is switched at a fast rate (60 Hz – 2 kHz).

In the past solenoid valves were driven using a transistor or op amp in linear mode. This worked well to control the valve as a directly proportional voltage signal could be easily controlled using feedback. The negative of this technique is that it generates a great deal of heat, is inefficient, and requires a larger enclosures since the output device is operated in between cutoff and saturation and is behaving like a variable resistor constantly having to dissipate the power not used by the load as heat.

PWM uses the output device digitally and therefore the device is either on or off. Using this technique the output device supplies a series of pulses of the same voltage level to the load. Since transistors are very efficient when either on or off, much less heat is dissipated. By varying the duty cycle (on time/switching period) the output effectively can emulate an analog signal, especially at the higher switching frequencies through a solenoid valve coils inductance.

Current feedback can be used to more effectively control the valve. With a known current flowing through the valve coil, the valve spool position can be precisely determined. The added advantage of this method is that it is independent of temperature.

19.1.1 Dither

Dither is a small modulation of the PWM signal. This is intended to compensate for stiction and hysteresis by continually changing the PWM signal slightly and thus keeping the valve spool in constant motion. This can dramatically improve the valve performance by improving response to small signal changes.

The following oscilloscope images illustrate both the PWM voltage and current waveforms. Also illustrated are the effects of varying PWM duty cycle and of adding dither.

20.0 CAN & SAE J1939

• Each device added to the J1939 manager represents a physical device on the bus.• So a "local device" represents the local mobile controller. This is

the message the controller will be *transmitting*.See the "local device" checkbox in the general tab.

• A non-"local device" represents a physical device on the bus. Thus its "Tx Signals" are what the device is sending and the mobile controller is receiving.

• Thus you should generally add one "device" to the tree to represent each device that is on the physical bus, including the "local" device.

• Also make sure you have the "local device" checked for the node that you want to use to transmit signals. While this is not intuitive at first, it makes complete sense once you are aware of it.

• There are no function blocks and everything happens automatically in the background. You just get scaled variables you can read or write from code.

• All transmission happens automatically per the configuration for each PGN. The "TransmissionMode" tab specifies the interval. Relevant options are "Change of State" and "Cyclic", but the default is change of state so the packet will not be sent unless one of the variables changes (i.e. from your code). Cyclic is the more traditional J1939 method and better for testing.The "I/O" mapping tab represents all the variables available in the device. These can be used in code for either inputs or outputs depending on whether it is a transmitted or received packet.

• You can automatically convert and scale variables by clicking on the SPN in the "Tx Signals" page, and then enabling the "Conversion" option. This lets you deal in engineering units (i.e. %, rpm, mph, etc) as opposed to the raw data bytes.

• Variables in the I/O mapping tab will not be updated unless physically used in code. This is an optimization done by the 3S compiler to reduce computation for unused variables. For debugging, you can check the "Always update variables" box and it will instruct the compiler/debugger to always display and update the values.

• The CAN "Network" option is base-zero. Thus Network 0 represents the first CAN bus, Network 1 represents the second CAN bus, and Network 2 represents the third.

21.0 INPUT STATUS, FEEDBACK, AND DIAGNOSTICS

A fault table is integrated in the IDE. Please see the below samples. When a fault occurs, an exclamation will come on the “Fault Table” icon indicating “Diagnostic message available”. If there is an active fault that relates to a PWM, analog, or frequency channel, then the respective icon will also display the red triangle as well. One message is displayed at a time in the “Fault Table Status” tab. When Acknowledge is selected the current fault is cleared and the next fault is displayed. If the fault cannot be cleared, it will remain until the condition is fixed.

24.0 FAULT CONDITIONS

Note: That while every effort has been taken to assist in identifying faults and providing a system to manage these faults, there is still the possibility of faults occurring that are not detected. The system designer must take this into account. This system is intended to assist with faults but is not intended to take the place of a safety system.

The controller features a highly refined fault management system. The system consists of a fault table of predefined system faults. All of the faults are mapped to addresses that are directly accessible in the application control program. There is also a reserved area for user defined IEC faults in this section. This is very flexible as all faults can be easily scanned through in one area of the environment. Both the predefined System Faults and the User Faults feature active and historic fault indication. Please see below:

Fault table indicating User and System faults

The range limits for many of the faults have default values that can be overwritten in the appropriate I/O configuration tab. Please see below:

Note in this example the range limit for an analog input is highlighted (34,000 mV), this is used for defining the appropriate range limit and if exceeded the corresponding fault will trigger if active.

HFX Product Family


The System Configuration I/O mapping contains the following:

A set of Global fault status variables to aid in managing faults. This consists of active and historic faults, a fault count, as well as a means to clear the faults. There is also a Fault Monitor where specific faults can be monitored. See below:

Note: the location of Global Fault Status and Fault Monitor shown above.

The following are the predefined faults:

VE5_max and VE5b_max – indicates the sensor_supply_1/2 are shorted to something above 5V (i.e. 12V power).

VE5_min and VE5b_min – indicates the sensor _ supply_1/2 is shorted to ground.

VE5ab_OOR - Both sensor supplies are "out-of-range". So if you short both high or short both low it will occur. It is functionally (VE5_max OR VE5_min) AND (VE5b_max OR VE5b_min).

COPfail is active - This is the system/firmware COP (computer operating properly) fault, AKA watchdog.This will only occur if there is a bug that causes the firmware to lock up or not trigger the COP approximately every 100ms.

RTI is active – This indicates that one of the internal firmware loops is not executing (1ms/5ms/50ms). – Basically this is similar to a COP for each of our internal loops.

RTI2 is active – As above.

RTI3 is active – As above.

Adloss is active – This occurs if the ADC routine is not running for some reason (similar to a COP overseeing the ADC operation).

Interrupt is active – This is caused if an invalid/unhandled interrupt is ever executed.

flash_fail is active - CPU hardware error.

RAM_fail is active - CPU hardware error.

HWID_fail is active - 2 specific resistors are present on the PCB. There value is used to identify the PCB hardware version. If these are at an unknown value, this fault will trigger.

J1939_Tx(x)Fail is active – Currently unsupported in CODESYS.

J1939_Rx(x)Fail is active - Currently unsupported in CODESYS.

DevDesc_error is active - This indicates there is a mismatch between the firmware and CODESYS device description.xml.

Illegal_flash write is active – This is an indication that CODESYS is attempting to write to a restricted address in flash.

Cpu_addr_err is active – This fault occurs if the CPU attempts to read or write an illegal or mis-aligned address. CODESYS will trigger this fault if you don't do a clean all.

Illegal_instr is active – This is similar to cpu_addr_err; however, it is for illegal instructions encountered by the CPU

FPU_exception is active – This fault is not supported by our hardware.

HFX Product Family


MRAM_fail is active – This indicates a detected CRC error or other problem with the MRAM used to store RETAIN variables. If this error occurs it is a major hardware failure.

PWMx_loss control is active – This is an indication that an output channel has failed. It should occur if the PWM driver fails in a shorted condition. It indicates that the program is instructing the output off, but the output is still flowing current. When this occurs it will then trip the secondary protection which is the internal solid state relay. This fault may also occur if a higher than supply voltage is placed on the output pin as this will cause reverse current to flow (through the body diode of the high side FET), which should be detected and thus trip the solid state relay.

CODESYS exception is active - CODESYS has its own exception implementation. Take for example the watchdog you can enable for each task. If you set enable the task watchdog and violate it then CODESYS throws an exception and displays an error message in the IDE and this fault will mirror that activity.

CODESYS watchdog is active - slightly different. This is monitoring the internal CODESYS task in firmware that executes all things CODESYS. Subtly but significantly different from the watchdog you enable in CODESYS via the IDE. This will happen if CODESYS locks up for any reason. Take for example you write a while(TRUE) loop in IEC code. Since everything runs from a single context, CODESYS will never see that the while(TRUE) loop has locked up, but the operating system will and inturn trigger this error. The watchdog time for this is configured in "CODESYS Runtime Watchdog" under System Config Configuration tab. The default for the "CODESYS watchdog" is 2 seconds so your individual task watchdog should be less.

CODESYS low mem is active - running low on CODESYS memory. There is 16KB of internal "dynamic" memory that is allocated to CODESYS – This is used for all of their code. There is information about this on the EDIS "Debug Sys" page.

CODESYS out of dn mem is active - similar to low memory fault above, but this is when the operating system is out of dynamic memory.

CODESYS bad pointer is active - CODESYS internal code calls a function that checks if memory is good.

CODESYS target mismatch – The CODESYS target description does not match the firmware.

Over Frequency – Aggregate frequency measured exceeds 200 kHz?

Batt_Low – This occurs whenever the supply voltage drops below 6 V for more than 5 seconds.

Batt_High – This occurs whenever the supply voltage exceeds 32 V for more than 3 seconds.

PWM1_2A Short to battery – This fault indicates when output channel 1(2A) has a short to the battery.

Note: That the controller is comparing commanded current value to the measured value to evaluate for the fault. The default current value is 25 mA but can be overwritten in the configuration of the unit.











HFX Product Family






PWM9_2A Short to battery – This fault indicates when output channel 9 (2A)has a short to the battery.













Note that the controller is comparing commanded current value to the measured value to evaluate for the fault. The default current value is 25 mA but can be overwritten in the configuration of the unit.











HFX Product Family










PWM1_2A Open circuit or Low-Side drive grounded – This fault indicates when there is an open circuit on output channel 1(2A). The controller is comparing the commanded current value to the measured value or checking for a ground short on the output. The default values can be overwritten in the configuration of the unit.





PWM6_2A Open circuit or Low-Side drive grounded – This fault indicates when there is an open circuit on output channel 6(2A). The controller is comp aring the commanded current value to the measured value or checking for a ground short on the output. The default values can be overwritten in the configuration of the unit.





HFX Product Family




PWM13_2A Open circuit or Low-Side drive grounded – This fault indicates when there is an open circuit on output channel 13(2A). The controller is comparing the commanded current value to the measured v alue or checking for a ground short on the output. The default values can be overwritten in the configuration of the unit.












HFX Product Family


PWM1_2A Over Current – High-Side current measured on output 1(2A) is greater than the hardware limit or greater than a default Max current of 2000 mA. The default current values can be overwritten in the configuration of the unit.


















HFX Product Family








PWM1_2A Loss of Control – This fault indicates that current or reverse current exceeding a default 75 mA is flowing without any commanded output current on the channel.

PWM2_2A Loss of Control – This fault indicates that current or reverse current exceeding a default 75 mA is flowing without any commanded output current on the channel

PWM3_2A Loss of Control – This fault indicates that current or reverse current exceeding a default 7 5 mA is flowing without any commanded output current on the channel

26.0 DEVICE COMMUNICATION TROUBLESHOOTING

The following is a list of things to check, in order of priority, if you are having problems connecting to your controller from Pro-FX Control.

1. Make sure the device is powered up. You should see a green light on LED A of the device. It is okay if this is flashing (this just means the controller is currently in run mode).

2. Make sure the USB port is connected and Windows has properly loaded the drivers. In the device manager you should see under "Ports" an entry that says "Mobile Controller: Enhanced COM Port".

3. Make sure that the gateway.cfg file has been properly installed per the instructions in this document. Installation of an alternate CODESYS device gateway may have overwritten this file.

4. In the Pro-FX Control "Communication Settings", select "None" for the "Filter". Then rescan for the device. If something new shows up then it could be that the device variant being used by your project is different than the connected device. Pro-FX Control will only let you connect to a device variant that matches the configuration of your project. To switch to the appropriate device, right click on it in the "Devices" project tree and select "Update Device".

5. Stop and start the gateway. Plug and unplug the USB port.

6. Restart Pro-FX Control.

7. Restart your PC

8. In some cases Windows will automatically assign a high COM port number to the USB device. If the device manager shows something higher than "COM20" then you should reassign it to something lower. Then restart the gateway and unplug and plug the USB port.

9. Each time a unique mobile controller is connected to your PC, Windows will provide 2 new COM port numbers. In some cases Pro-FX Control appears to have problems automatically discovering the device's COM port when the value gets too high. In this case there are 2 options:

• From the device manager, click the COM port's properties, select "Port Settings" tab, click "Advanced", and select a "Com Port Number" that is below COM20. Then restart the gateway and replug the USB device to ensure changes are applied properly.

• You can alternately edit the gateway.cfg to manually assign your device's COM port number. Open the gateway.cfg file located in the directory ProgramFiles (x86)\3S CODESYS\GatewayPLC and change the line that begins with "Com.0.Port". After making this change, restart the gateway.

Note: After making this change, your installation will no longer automatically detect other controllers so this must be repeated for all unique controllers that are connected to your PC.

27.0 DEVICE RECOVERY

On HFX, short PWM1_2A *AND* PWM2_2A to VBAT (must be > 11 V). Then power the system with either the service tool running, or attempt to connect via CODESYS within 3 seconds after powerup. This will prevent the CODESYS application from running and then you can recover it.
